Label=(label-name-list)

    Specifies the 1- to 6-character string with which the volumes
    of the backup file have been labeled. The Label qualifier is
    applicable only to tape volumes. You must specify one or more
    label names when you use the Label qualifier.

    You can specify a list of tape labels for multiple tapes. If you
    list multiple tape label names, separate the names with commas,
    and enclose the list of names within parentheses.

    In a normal recovery operation, the Label qualifier you specify
    with the RMU Recover command should be the same Label qualifier
    you specified with the RMU Backup After_Journal command to back
    up your .aij files.

    The Label qualifier can be used with indirect file references.
    See the Indirect-Command-Files help entry for more information.
